close-to-home bad practice

Today, the publishers of my book [Key Concepts in e-Commerce] sent an email to all lecturers on their mailing list informing them of the new text [good practice].

Sadly, the message included a link to the book's web page - which, when clicked on, returned a 'page cannot be found' message.

Harrumph - hope it doesn't cost me sales, I have an expensive wife and large mortgage to support.

Footnote : it was sorted out inside a couple of hours.
